HOSE-NOZZLE HOLDER.

SPECIFICATION forming part of Letters Patent No. 479,841, dated August2, 1892.

Application filed January 28 1892. Serial No. 418,988. (No model.)

To all whom it may concern.-

Be it known that I, CYRUS R. ROBINSON, a citizen of the United States,residing at East Concord, in the county of Merrimac and State of NewHampshire, have invented certain new and useful Improvements inHose-Nozzle Holders; and I do hereby declare the follow- .ing to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My present improvements relate to fire-hose supports of the constructiondescribed and claimed by me in United States patents, dated July 16,1889, numbered 407,118, and April 8, 1890, numbered 425,256, the objectsbeing, essentially,to facilitate the manipulation of the extension-rodand toinsulate the handle-bars, in order to prevent the operator fromreceiving an electric shock in case the stream should accidentally openan electric circuit.

In the old method of handling hose the hands of a fireman are in direct,contact with the metallic nozzle, and several instances have beenrecently reported where the fireman holding the nozzle was instantlykilled by a current of electricity following the stream to the nozzleand grounding through the nozzle-man. In this respect, as well asothers, my improved nozzle-holder possesses an advantage over the oldmethod of holding fire-hoseviz., the metal of which it is composed beingwholly, or the larger proportion, copper, and being secured in directcontact with the nozzle, it becomes a powerful conductor and carries anelectric current the shortest cut to ground, instead of using the man asconducting agent, the handles of my improved holder being perfectlyinsulated and so conveniently arranged that no occasion arises fortouching the nozzle,

. which enables a fireman to direct a stream in safety even amongheavily-charged electric wires.

The invention will be fully set forth in the following specification andclaims, and clearly illustrated in the drawing accompanying the same,which consists of a broken elevation showing a portion of a nozzle andhose connected and attached to my improved support or holder, theextension-rod being fully extended.

A represents a portion of a nozzle; B, the coupling by which it isconnected to the hose 0. The hose-carrying brackets D D, the curved rodsE, connecting the same and forming handles by which to steady the hose,do not vary in any essential degree from the same parts shown anddescribed in the pre vious patents referred to above, the brackets Dbeing provided with straps F, which are buckled around a hose, and thebracket D being slotted at d at each side to receive the studs 1),projecting from the sides of the coupling B diametrically opposite oneto the other, the said bracket being also provided with the spring-stopbolts d for preventing the accidental displacement of said studs 1) andthe hook d shown and described in the-flast of the two patentspreviously ment-ioned--viz., No. 425,256.

In the present instance the brackets D D are mounted upon a copper tubeG, which carries the extension-rod H, having near its lower end a collarh and provided at its extreme lower end with athreaded projection h,adapted to carry the threaded socket of my improved crooked point H.This form of point is preferable to the straight previously patented, asthe holder when in service is usually placed at an angle and the presentform of hook or point will prevent the movement of the holder even whenplaced in nearly a horizontal position, and in order that the hook mayalways point downward I provide a groove 72 in the rod H, runninglongitudinally, and a screw J in the lower bracket D, which enters saidgroove, as shown. The rod H is locked either within said tube G or whenextended, as shown, by means of a suitable spring stop K, enteringopenings 7L3, formed for the purpose in said rod.

The handles 6 are covered with a strong insulating material, and theentire hose-holder being composed of brass and copper and at all timesin close connection with the nozzle, a metal circuit is thus producedhaving the least possible resistance. Hence any current of electricitywhich strikes the nozzle will follow the metal instead of the man.

Another advantage in my improved extension-rod is the convenient meansof adjustment to various lengths as a pipeman may require, which was notpossible in using my former extension-rod, as that was detachable anddid not pass into avtube as does the rod H in the present case, theholes it being placed at frequent intervals, the spring-stop K holdingthe rod at any point desired.

Having described my improvements, What I claim is In a fire-hose supportupon which metal brackets and straps are used for attaching the hose,the herein-described tubular connection, upon which said brackets aremounted, an extension-rod mountedin said tubular connection providedwith a longitudinal groove adapted to receive a screw or pin projectingtension-rod, and the insulated handles formed upon side-bars connectingthe said hosebrackets, all substantially for the purpose set -forth.

In testimony whereof I affix my signature in presence of two witnesses.
